WORSLEY, OF AUDENSHAW,

SPECIFICATION forming part of Letters Patent No. 674,078, dated May 14, 1901.

Application filed July 15,1899.

To all whmn it may concern:

Be it known that I, FRANCIS CREE, S12, a subject of the Queen of Great Britain and Ireland, residingat Denton, in the county of Lancaster,England, haveinvented Improvements in W'inding Thread, of which the following is a specification.

Thisinvention relates to the winding of sewing-thread into a long cylindrical cop with IO conical ends, more especially for usein lockstitch sewing-machines provided with revolving carriers for the under or lock thread.

Figure 1 on the drawings is a longitudinal section of a long cylindrical cop of sewingthread with conical ends wound in accord ance with my invention. Fig. 2 is a similar view showing the same bent or curved into a circular form to fit into the revolving carrier of the lock-stitch sewing-machine. Fig. l is an outside view of the cop, and Fig. 2 aview of the pointed conical end of the cop, showing the crossing of the coils. Fig. 3 is a side elevation of an apparatus for winding such cops of sewing-thread. Fig. 4 is a plan view of the same; and Figs. 5 and 6 are detached views, hereinafter more particularly referred to.

The improvementin winding thread according to my invention consists in laying the end a: of the thread along the spindle from point 0 to butt and then winding the thread in the form of a long cylindrical cop (see Fig. 1) built up of a series of cones of crossed and superposed coils, so that one end aof the cop forms an obtuse cone and the other end I) a reversed or hollow cone. The cop thus produced has the delivery end 05 of the thread extending from the hollow rear or butt end I) through the hollow center and projecting out at the nose end a, so that as it is drawn 0% at the 0 rear end and out at the nose the cop will remain of the same diameter and solidity, but will dimish gradually in length at the rear end 6.

My invention enables a cop containing a 5 very considerable length of sewing-thread (say from one thousand to fifteen hundred yards) to be used as the under or lock thread of a sewing-machine in a continuously-revolving carrier without any tendency to cause Serial No. 723,994:- (No model.)

the thread to snarl or kink by overtwisting. The machine by which I propose to wind the sewing-thread in this manner forms the subject of an application for a patent filed by me November 14,1899, Serial No.736,987, and consists principally of a headstock 0, (see Figs. 3 and 4,) carrying a revolving spindle-holder d,

in combination with a reciprocating threadguide 6, mounted on a carriage f,sliding horizont-ally upon a bed-plate g and actuated by means of a slowly-revolving screw it. The spindle-holder d is fitted with a small grooved pulley t, driven rapidly by an endless band from a larger pulley, which is actuated by foot, hand, or other power. The spindle 7c is tapered and its butt-end fits tightly in the holder d, its extreme end being steadied by a springsupport Z. This end is fitted with a loose cone m, between which and the thinner end of the spindle 7c the end 00 of the thread to be wound is held tight. The thread is laid along the length of the spindle is from the tip to the buttend,which is provided with a cone a. The bedplate g extends longitudinally below the spindle k, and the carriage f, which slides along the bed-plate g, supports the thread-guide e, which is in the form of a lever moving to and fro horizontally over the spindle in. This thread-guide e is moved horizontally in one direction by means of a rocking bar 0, acting against a fingerp, and in the reverse direction by means of alcoiled spring q. The rocking bar 0 is actuated by a leverr, (see also end view Fig. 6,) which is held by the spring q against a double cam s, drivenby an endless band tfrom the head-stock spindle-carrier d. In order that the guide e may be so moved as to lay the thread on lines the most effective to hold the superposed and crossed coils, as hereinafter described, the cam .9 should have the parabolic curves shown.

The screw it for traversing the thread-guide carriage fis caused to make a portion of a revolution intermittently by means of a jointed grip motion u, (see also end view Fig. 5,) connected to a lever 12, actuated by an eccentric 95 or cam 10, mounted on the spindle-carrier d, and the working surface of this eccentric or cam w is made conical, as shown at m, Fig.

4, so that by shifting it endwise on its spindle d by means 'of the regulating-screw y the diameter of the cop may be varied.

The half-nut 2, (see Fig. 3,) which works on the screw it, is hinged to the carriage f, so that it can be lifted out of gear with the screw h when it is desired to move the carriage by hand to the extreme right, so as to commence winding a fresh cop. The slowly progressive motion of the thread-guide carriage and the to-and-fro motion of the thread-guide will cause the thread to be wound on the spindle in a series of superposed cones from end to end in the form shown at Fig. 1. The thread after being laid along the spindle from tip to butt and the winding begins will be laid in spiral coils extending from the base to the tip of the cone and back again, Figs. 1 and 2*, to form the superposed cones, and the successive spiral coils will cross and bind each other in place, and as this crossed spiral coiling is moved progressively forward from butt toward the tip of the spindle a long cylindrical cop is formed of such a character that it can be bent around into a curved form without breaking. As the delivery end of the thread extends from the base of the cop through the interior and is drawn out at the nose, it will be drawn off from the hollow base without snarling or kinking.

I claim as my invention- 1. The mode herein described of winding thread into long cops, consisting in laying the end of the thread along a winding-spindle from tip'to butt and then winding the thread spirally backward and forward into superposed conical layers throughout the entire length of the cop from base to tip, crossing successive coils over each other and advancing the crossed spiral coiling progressively forward with the delivery end of the thread lying in the hollow center.

2. As a new article of manufacture, a long hollow cylindrical cop with conical nose and hollow conical base from which in use the thread can be drawn through the interior of the cop, the thread being laid spirally backward and forward in successive layers, and the spirals crossing and binding each other, the delivery end of the thread extending from the conical base through the hollow interior of the cop and projecting at the nose whence itcan be drawn off, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRANCIS CREE, SENIOR.
